Asadu, C.Diels, J.Vanlauwe, Bernard[A comparison of the contributions of clay, silt and organic matter to the effective CEC of soils of subSaharan Africa]A comparison of the contributions of clay, silt and organic matter to the effective CEC of soils of subSaharan Africa
Diels, J.Aihou, K.Iwuafor, E.Merckx, R.Vanlauwe, Bernard[Evaluating options for soil organic carbon maintenance under intensive cropping in the West African savanna using the Rothamsted Carbon (RothC) model]Evaluating options for soil organic carbon maintenance under intensive cropping in the West African savanna using the Rothamsted Carbon (RothC) model

Characterization of decomposition characteristics is important for sound management of organic residues for both soils and livestock, but routine residue quality analysis is hindered by slow and costly laboratory methods. This study tested the accuracy and repeatability of near-infrared spectrosc...


Shepherd, Keith D.Vanlauwe, BernardGachengo, CNPalm, C.A.[Decomposition and mineralization of organic residues predicted using near infrared spectroscopy]Decomposition and mineralization of organic residues predicted using near infrared spectroscopy

Data from the derived savanna zone in southern Benin indicated that some intensive cropping systems (maize/Cajanus and maize/Mucuna relays; maize/cotton with Senna siamea hedgerows) returned about 12 Mg DM ha-1 year-1 of plant biomass to the soil. This compared favorably with the 8 Mg DM ha-1 yea...

Maintenance of soil organic matter (SOM) at levels that sustain optimal supply of soil nutrients and enhance efficiency of externally added fertilizers is a major challenge for smallholder farming systems of southern Africa. A study was conducted to quantify the interactive effects of organic res...


Mapfumo, PaulMtambanengwe, F.Vanlauwe, Bernard[Organic matter quality and management effects on enrichment of soil organic matter fractions in contrasting soils in Zimbabwe]Organic matter quality and management effects on enrichment of soil organic matter fractions in contrasting soils in Zimbabwe

Although the West-African moist savanna zone has a high potential for crop production, yields on farmers' fields are, on average, far below this potential, mainly due to the low use of external sources of nutrients. Since the mid-1990s, it has become clear that in order to upgrade crop production...
